PORTFOLIO.

Application filed October 30, 1926. Serial No. 145,123.

This invention aims to provide a portfolio having the inner ends of itscover members connected by an element on the inner side of which lattera binder support is secured, and to provide binders any one of which maybe readily mounted on orremoved from the binder support so that themaufacturc of ortfolios may be cheapened and simplified and also toprovide a portfolio into which any one of a variety of binders withtheir sets of leaves may be inserted.

Another object of the invention is to [no vide a portfolio having abinder support secured therein which has holding means for supporting abinder in such a manner that the latter cannot become detached from itssupport without positively releasing the holding means, andsimultaneously exerting pressure on the binder itself.

With these and other objects in view which will become apparent as thespecification proceeds, the invention is hereinafter more fullydescribed with the aid of the accompanying drawings, in which:

Figure 1 is a general view of a portfolio, and

Figure 2 illustrates the same portfolio being utilized as a stand.

Figure 3 is a partial View of the invention showing the binder support.

Figure 4 shows the side of a binder and binder support, and the elementby which the side members are connected in section.

Figure 5 is a partial View of a binder. and

Figure 6 is a section on the line VI--VI of Figure 3.

Referring to the drawings, 1 designates a portfolio having cover members2 and 3 connccted at their inner ends by an element 4;. To the latter abinder support 5 is attached as by rivets 6. Integral with the bindersupport are forwardly projecting loops 7, and the upper end of thesupport cut away at 8 to permit the forwardly flexed end 9 ot the spring10 to project between the upper margins 8 of the support. The lower end.ot the spring terminates between the inner surface of the element 4; andthe back of the binder support 5, and held in position by one of therivets 6 employed for connecting the binder support to the cover element4.

The binder 11 is usually substantially channel-shaped insectiou, so thatthe leaves 12 may be secured in any desired manner between the oppositesides 11 of the binder; and the central portion 11 of the binder,

It will be noted that the fingers 14 are so positioned that when theyare fully in engagement with the loops 7 that the upper end of thecentral portion ll of the binder is immediately beneath the forwardlyflexed end 9 of the spring 10, so that should pressure be exerted underthe binder the latter will not become disengaged from its support unlessthe forwardly flexed spring end 9 is snnultaneously depressed.

ln Figures 1 and 2 the portfolio 1 de plcted is of the type on which theconstruction hereinbefore described is utllizedi though obviouslyvariations may be made in the cover member construction. In theportfolio 1 one of the cover members 3 has a flexible portion 15 thereonwhich is. of sufiicient length to fold around the outer edges of theleaves 12. At the other end of the flexible portion is a flap 16 whichis in turn secured to an extension 17 by a joint 18. The cover member 2,the flap 16, and the extension 17 are provided with fasteners 19 so thatthe portfolio may be secured either in open position as indicated inFigure 2 or in closed position. I

On account of the fastening means between the binder support and thebinder supporting the latter towards both its ends the cover members 2and 3 may be turned downwards into the position indicated, in Figure 2without an} danger of impairing the cilicacy of the fastening means. Itwill also he noted that this construction permits of several bindersbeing carried and successively mounted in the one portfolio, therebyminimizing the amount of equipment that a salesman need carry with him.

lVhile in the foregoing the preferred em bodiment of the invention hasbeen described and shown it is understood that the construction issusceptible to such modifications as fall within the scope of theappend-edelaims.

What I claim as my invention and desire to secure by Letters atent is:

1. A portfolio comprising a cover, a sup porting plate connected to thecover, a binder including a member superposed on and in contact withsaid supporting plate, one of said contacting members having an integralloop projecting from its inner face and the other said member having atongue projectlng from its mner face and extending through said 100p,and means for preventing relative movement between the supporting plateand binder tending to Withdraw the tongue from the loop.

2. In a portfolio, the combination with a cover and a binden of meansfor detachably connecting the cover and binder comp 'ising 1 asupporting plate secured to the cover and making surface contact with aportion ot the hinder, the contacting members of said plate and binderhaving interengaging means and a leaf spring extending between saidmembers and secured to one of then'n a portion of said spring engagingthe other said member to normally prevent disengagement of saidinterengaging means.
